ADVERTISING DEVICE.

Application 'flledMarch 17., 1922. Serial No. 544,555.

To all whom it may concern:

Be it known that we, FRANK A. Gnrr'r and ARTHUR E. Gnrr'r, citizens ofthe United States, and residents of Indianapolis, county of Marion, andState of Indiana, have'invented a certain new and useful AdvertisingDevice; and We do hereby declare that the following is a full, clear,and exact'description thereof, reference being had to the accompanyingdrawings, in which like numorals refer to like parts. This inventionrelates primarily to a unitary advertising device, although severalelements thereof may be otherwise utilized.

The chief object of this invention is to provide a construction whereina blaze or wave motion effect is secured without the use of inflammablematerial, thereby eliminating the danger of fire.

The chief feature of the invention consists in the association of arotary reflecting screen with a source of illumination,- which source ofillumination is adapted to rotate said screen.

Another feature of the invention consists in the rotation of theadvertising device by the illumination means.

The full nature of this invention will be understood from theaccompanying drawing and the following description and clalm.

In the drawings Fig. 1 is a perspective view of the advertising deviceas a unit.

Fig. 2 is an enlarged central sectional view.

of the advertising device. Fig. 3 is a to plan view of the same. Fig. 4is a develop view of the rotary reflecting screen.

In the drawings 10 indicates any suitable support and the angularbracket 11 is secured to said support by suitable means, such as thechain 12. The angular bracket 11' has an u wardly extending portion 13which provi es a central axis vand said extension 13 is in alignmentwith the chain support 12. The extension 13terminates in a amp socket 14which carries a lamp bulb 15. Current is supplied to the lampbulb- 15through the socket 14 by means of the osiare

current conducting wires preferably tioned in the tubular support 11 anherein not shown.

Herein there is illustrated a standard 16 which is suitably supportedupon the support 11 near the base thereof and is provided with anangular portion whichterminates in a point 17, said point being in axialalignment with the axial extension 13. A

frame-work consisting of a plurality of face forming frames 18 forms ahollow and tubular construction, the bottomof' which'iso en and the topof which is closed by the p ate 19 which is suitably a'pertured at 20 toform a plurality-of blades 21 which are positioned angularly of saidbody portion 19. The

central portion of the plate 19 is shaped to form a depression or socket22 which is adapted to receive the point 17. If desired, a suitable fanconstruction 23 may be associated with the underside of the top plate 19and it is to be understood that said fan construction has its bladesregistering with the blades 21 to form a continuation thereof, altho ughthe angle thereof may be changed if desired. In this manner with eitherof the foregoing constructions, the top 19 forms a propeller or fandevice and an axial current of air passing through the openings 20 inthe top- 19 will rotate said top and the face forming frame worktherewith by engaging the blade portions 21.

Each of the faces 18 of the hollow, tubular frame work maybe providedwith a trans parent or translucent closure 24 which may carry suitableadvertising matter. It is, of course, to be understood that the hollowtubular construction may be cylindrical, conical or barrel shape and thelike without departing from the broader features of the invention. Thebroad idea of utilizing a heating current of air which rises into thecolder portions of the air for rotational purposes is broadly o d andthe same per se is not claimed in this invention. The lamp 15 thussupplies illumination to the transparent or translucent material 24 toilluminate the advertising matter therein or thereon, and said lampalso, by means of the column of heated air which rises therefrom,rotates the tubular advertising framework.

radiating S-shapedarms, the inner and central ends of which are'suitablysecured together to'form a centralsupport. The outer and free end ofeach arm-1s secured'to its adjacent neighbors by suitable means, such asthe clips or rivets 27.. When thus secured there is formed a rotaryscreen having a plurality of curved openings 28 and an 0 ,n

base. There is also provided a sup ortmg member 29 having a point 30 anda ase 31,

and herein said supporting member 29 is sists in providing said rotaryscreen with an inner surface of reflecting or mirror qualities, wherebythe light received 'by-the armportions 26 will be reflected through theother apertures 28, thereby utilizing all of the light rays eitherbyradiation or by reflection. lhe construction of the rotary ro flectingscreen is such that the air heated by the lamp 15 passes u wardly andoutwardly from said'lamp. an rotates said screen in its upward movement.The heated air'thereafter passes upwardly in the manner hereinbeforedescribed and rotates the tubular framework. I

It will be readily apparent from the foregoing description that thedevice me be constructed of non-inflammable materi yet screen beingadapted to enclose a source of 1,4e 1,ose

the rotary screen is adapted to simulate a fire or a biaze behind theilluminated trans- 40 llucent or transparentv medium. Likewise therotary screen in its rotation darkens the transparent or translucentmedium and thereby simulates a wave efiect. It will also be rememberedthat the transparent medium is rotatably mounted and is rotated, but thedevice herein illustrated is such that the rates of rotation are not thesame and, therefore, there. will be an ever changing wave formation, dueto the difference in the speeds of rotation 'While the invention hasbeen described in considerable detail in the foregoing specification,said detailed description is to be considered illustrative andnotrestrictive in character and the many modifications thereof whichwill readily suggest themselves to those skilled in theart, as well asthose hereinbefore suggested, are all considered to be within thepurview of this invention, reference being adto the appended claim.

The invention claimed s:

A rotatable screen comprising a plurality of radiating $-shaped armshaving their inner ends secured-together and tieir outer ends securedtogether, the inner ends pivotally. sup orting the rotary screen and theouter end; forming an o ening, each of said arms having an inner reecting surface, said illumination. 'In witness whereof, we have hereuntoaffixed our signatures.
